Systems and methods for facilitating online authentication from untrusted computing devices

1. A computer-implemented method for facilitating online authentication from untrusted computing devices, at least a portion of the method being performed by a proxy server comprising at least one processor, the method comprising:

receiving, at the proxy server, a request from an untrusted computing device to access an online service;

retrieving, at the proxy server, authentication information for accessing the online service from a database;

using the authentication information to log into the online service at the proxy server without exposing the authentication information to the untrusted computing device;

proxying traffic between the online service and the untrusted computing device at the proxy server without exposing the authentication information to the untrusted computing device by:

retrieving content from the online service at the proxy server;

embedding the content retrieved from the online service at the proxy server within a web page;

transmitting the web page containing the embedded content from the proxy server to the untrusted computing device.

2. The method of claim 1 , further comprising, prior to retrieving the authentication information for accessing the online service, receiving user-account authentication information from the untrusted computing device.

3. The method of claim 2 , wherein the user-account authentication information comprises multi-factor authentication information.

4. The method of claim 1 , wherein retrieving the content from the online service at the proxy server comprises retrieving a web page from the online service at the proxy server.

5. The method of claim 1 , further comprising:

converting, at the proxy server, the authentication information for accessing the online service into a human-readable image; wherein the human-readable image is in a format that enables a user of the untrusted computing device to complete an authentication process required to access the online service but prevents computing devices from extracting useful information;

transmitting the human-readable image from the proxy server to the untrusted computing device.

6. The method of claim 5 , wherein the method further comprises at least one of:

adding visual noise to the human-readable image;

transforming at least a portion of the human-readable image.

7. The method of claim 6 , wherein transforming at least a portion of the human-readable image comprises:

rotating at least a portion of the human-readable image;

stretching at least a portion of the human-readable image;

tilting at least a portion of the human-readable image.

8. The method of claim 1 , further comprising providing a website that allows a user to:

request a human-readable image that is in a format that enables the user to complete an authentication process required to access an online service but prevents computing devices from extracting useful information;

add authentication information for accessing an online service to the database;

edit authentication information for accessing an online service stored in the database;

delete authentication information for accessing an online service from the database;

request access to an online service.

9. The method of claim 1 , wherein the authentication information for accessing the online service is associated with a user account for the online service.

10. A computer-implemented method for securely providing authentication information for accessing online services to untrusted computing devices, at least a portion of the method being performed by a proxy server comprising at least one processor, the method comprising:

receiving, at the proxy server, a request from an untrusted computing device for authentication information for accessing an online service;

identifying, at the proxy server, computer-readable authentication information for accessing the online service;

obtaining, at the proxy server, the computer-readable authentication information for accessing the online service;

converting, at the proxy server, the computer-readable authentication information for accessing the online service into a human-readable image, wherein the human-readable image is in a format that enables a user of the untrusted computing device to complete an authentication process required to access the online service but prevents computing devices from extracting useful information;

transmitting the human-readable image for accessing the online service from the proxy server to the untrusted computing device to enable the user of the untrusted computing device to complete the authentication process required to access the online service.

11. The method of claim 10 , wherein:

identifying the computer-readable authentication information for accessing the online service comprises searching a database for computer-readable authentication information for accessing the online service;

obtaining the computer-readable authentication information for accessing the online service comprises retrieving the computer-readable authentication information for accessing the online service from the database.

12. The method of claim 10 , wherein the method further comprises at least one of:

adding visual noise to the human-readable image;

transforming at least a portion of the human-readable image.

13. The method of claim 10 , wherein transforming at least a portion of the human-readable image comprises:

rotating at least a portion of the human-readable image;

stretching at least a portion of the human-readable image;

tilting at least a portion of the human-readable image.

14. A system for facilitating online authentication from untrusted computing devices, the system comprising:

a database for storing authentication information for accessing an online service;

an access module for:

receiving, at the proxy server, a request from an untrusted computing device to access the online service;

retrieving, at the proxy server, authentication information for accessing the online service from the database;

using the authentication information to log into the online service at the proxy server without exposing the authentication information to the untrusted computing device;

proxying traffic between the online service and the untrusted computing device at the proxy server without exposing the authentication information to the untrusted computing device by:

retrieving content from the online service at the proxy server;

embedding the content retrieved from the online service at the proxy server within a web page;

transmitting the web page containing the embedded content from the proxy server to the untrusted computing device;

at least one processor configured to execute the access module.

15. The system of claim 14 , further comprising a conversion module for converting the authentication information for accessing the online service into a human-readable image that is in a format that enables a user of the untrusted computing device to complete an authentication process required to access the online service but prevents computing devices from extracting useful information.

16. The system of claim 14 , further comprising a website module for providing a website that allows a user to:

request a human-readable image that is in a format that enables the user to complete an authentication process required to access an online service but prevents computing devices from extracting useful information;

add authentication information for accessing an online service to the database;

edit authentication information for accessing an online service stored in the database;

delete authentication information for accessing an online service from the database;

request access to an online service.

17. The system of claim 14 , further comprising a user-authentication module for authenticating a user of the untrusted computing device.
